Empty and unloved, some of the world's priciest properties have been forsaken by their owners, including royal residences, grand country houses and luxurious ranches. Left to languish, we take a look at eight of the most expensive abandoned mansions, from a sprawling 'calendar house' with 365 rooms to the haunted Pink Floyd manor. Click or scroll on to uncover their secrets...

Built in 1890, this empty stately mansion in Augusta, Georgia comes with a pretty amazing history. Offering eight bedrooms and six bathrooms, the sprawling home may be somewhat faded from its illustrious heyday when it was at the heart of high-society life, but its prestige is still evident. 

The palatial property is said to have regularly hosted the 27th President of the United States, William Howard Taft, in the early 20th century. Even with dusty floors and graying woodwork, it's not hard to imagine the mansion's former grandeur. This reception space is nothing short of spectacular, from the Art Nouveau-style glass light fixtures to the magnificent leaded windows and detailed paneling.

At the heart of the Queen Anne-style house, this grand carved staircase takes center stage – talk about making an entrance! Commissioned in the late 19th century by businessman Landon Addison Thomas Jr, the property has been in the same family for over a century, however, it's now listed with Blanchard & Calhoun Real Estate for a cool $1.5 million.

This imposing Italian Renaissance Revival mansion in Virginia was built in 1912 for business leader and philanthropist Major James H Dooley at a cost of $2 million, a hefty $51 million in today's money. No expense was spared on the ultra-luxurious property, which took 300 artisans eight years to finish.

A romantic escape for Major Dooley and his beloved wife Sarah, Swannanoa was kitted out with furnishings worthy of a billionaire, including exquisite Carrara marble flooring and wall panels, along with gold plumbing fixtures. The home's wow-factor feature is a stunning 4,000-piece Tiffany stained glass window featuring a depiction of Mrs Dooley that cost the equivalent of $64,000 when adjusted for inflation. 

The envy of the neighborhood, the mansion featured all the latest mod cons. As well as being the first property in the area to have electricity installed, Swannanoa had a cutting-edge elevator and dumb waiter, and upon entering the property, guests were wowed by the paneled entryway and splendid marble staircase. 

The Dooleys summered at the property until Major Dooley's death in 1924. Mrs Dooley died in 1926 and Swannanoa passed to her late husband's two sisters, who didn't waste any time getting rid of it. The mansion was sold for the knockdown price of $300,000 and converted into a country club, which opened in 1929 but closed in 1932 on account of the Great Depression.

The mansion was left empty for years. During the Second World War, the US Navy floated plans to purchase the property but was put off by the cost. Swannanoa finally found a buyer in 1944 when local businessman A. T. Dulaney acquired the dilapidated house for $60,100. He leased it to polymath Walter Russell and his sculptor wife Lao, who established a New Age university on the estate.

Russell died in 1963 and his wife continued to lease the property until her death in 1988, when it was repurposed as the Russell Museum. Owners the Delaney family shut the museum in 1998 and partly renovated the property, but the vacant Gilded Age mansion, which they describe as a 'money pit', still requires extensive work, though it does manage to function as a venue for weddings and other events.

A monument to shameless corruption, the Mezhyhirya Residence in the Ukraine was the official summer house or dacha for the Soviet leadership, and passed to the Ukrainian government following the dissolution of the USSR in 1991. Viktor Yanukovych moved into the property in 2002 shortly after his election as prime minister and went on to spend millions of dollars of ill-gotten cash on it.

Yanukovych was evicted from the residence following the Orange Revolution in 2005 but returned as prime minister in 2006. The politician had the property privatized the following year. The estate's Soviet-era buildings were demolished and work began on a five-story stone and timber palace designed by Finnish firm Honka, which is thought to have cost at least $10 million.

Yanukovych, who was elected president in 2010, splurged millions of dollars of taxpayers' money on the blingy interiors, purportedly ordering scores of gilt and crystal chandeliers at $100,000 a pop, $64,000 doors, a staircase clad in fine marble priced at an eye-watering $430,000, and more.

The no holds barred spending extended to the opulent bathrooms, which were fitted with the most expensive gold fixtures money could buy. Yanukovych installed an underground shooting range and dropped $3 million on a golf course. A pricey bowling alley and tennis courts were also constructed.

Yanukovych also had a garage complex built to house his vast collection of classic cars. Karma eventually caught up with the president, who was ousted by the Ukrainian Revolution in 2014 and fled the country. Wanted for high treason, Yanukovych is currently hiding out in Russia. His abandoned palace, a testament to the man's extravagance, is now a museum. 

Staying with corrupt leaders, Mobutu Sese Seko, the former president of Zaire, now the Democratic Republic of Congo, was just as free and easy with other people's money, lavishing $100 million on his 'Versailles in the Jungle', a luxe palace complex that was built in his home town of Gbadolite during the 1970s.

There was a swanky red-walled nightclub in the complex, which had a bar stocked with the best vintage champagnes, fine wines and spirits.  The Gbadolite complex also had several huge swimming pools, a five-star hotel for visiting dignitaries and a number of plush guesthouses to boot.

Mobutu was deposed in May 1997, having embezzled up to $15 billion. The ex-president fled to Morocco, where he died later that year. Gbadolite was looted and all its valuables were removed or destroyed. The jungle has since reclaimed the complex, which lies ruined and abandoned. 

The sprawling country house was built for copper tycoon Hugh Robert Hughes, who became known as HRH due to his suitably regal lifestyle. The mansion passed through several families and was last used as a private home in 1929, when it was sold to the highest bidder and converted into a boy's school.

Kinmel Hall became a spa for rheumatoid suffers in the 1930s and a military convalescent home during the Second World War. The mansion changed hands again after the war when it reopened as the Clarendon School for Girls. A fire in 1975 forced the school to relocate and Kinmel Hall was acquired and restored by businessman Eddie Vince, who used it as a Christian conference center.

There were plans to transform Kinmel Hall into a luxury hotel, but the project never came to fruition. In 2011, a mystery buyer bought the mansion for a bargain $1.9 million with the intention of developing the elusive hotel.

Kinmel Hall was added to the Victorian Society's Top 10 Most Endangered Buildings list in 2015 due to its worsening state. The current owner, who resides in the Cayman Islands, has pretty much left the grand mansion to wrack and ruin, and the restoration bill is now likely to cost in the region of $25 million. 

Back in 1983, before his epic downfall, Michael Jackson teamed up with Paul McCartney to record 'Say Say Say', and the former Beatle stayed at Sycamore Valley Ranch in California while the pair were recording the video. After visiting McCartney there, Jackson promised he would buy it someday and he acquired the ranch in 1988 for a purported $19.5 million.

Jackson renamed the property Neverland after the magical island in Peter Pan, and set about creating his very own amusement park. Jackson had two railways and a station (pictured) built to complement the Tudor-style six-bedroom mansion that came with the property and installed a petting zoo and numerous amusement rides. 

Neverland had everything from a Ferris wheel and pirate ship ride to a carousel and bumper cars. While Jackson was still universally adored, if thought to be a little odd, he hosted many events at the ranch, including the 1991 wedding of his close friends Elizabeth Taylor and Larry Fortensky.

In 2003, Jackson was charged with child abuse and Neverland Ranch was turned upside down by police searching for evidence, but the singer was eventually acquitted on all charges. Jackson complained of feeling “violated” following the search and vowed never to live at the ranch again.

In 2006, Neverland shut down and most of the staff were sent packing. Up to his eyeballs in debt by this point, Jackson struggled to hold onto the property. Investment firm Colony Capital bought a majority stake in 2008 for $22.5 million, and the ranch's amusement rides were removed. After Jackson's death in 2009, the ranch fell into disrepair and the property was put up for sale in 2015 with an asking price of $100 million.

Despite lowering the price to $67 million, the house remained unsold. In 2019, the harrowing documentary Leaving Neverland told the stories of two men, Wade Robson and James Safechuck, who allege they were sexually abused as children by the singer. Billionaire Ron Burkle finally snapped up the notorious property in December 2020 for a reported $22 million, with a view to developing the land.

During his stay at the manor, Morrissey claimed to have been visited by the ghost of a monk. The phantom would appear during the wee hours of the morning as if to wake people to pray. In fact, rumor has it that David Gilmour gave up the property because his wife Ginger was so freaked out by the paranormal activity, she refused to stay there. 

Tragedy struck at the manor in 2006 when Horn's wife Jill Sinclair was shot accidentally by their son Aaron, who was practicing with his air rifle and had no idea his mother was nearby. Sinclair fell into a deep coma and never fully recovered. Horn decided to sell up following the accident, and the property was bought by producer Mark White in 2009 for $15 million.

White invested in the studio but the house lay neglected for years. Trevor Bishenden aka TrevBish Photography captured the dilapidated interiors last year when the manor appeared to be completely abandoned with rising damp and wallpaper peeling off the walls. Fortunately, Hook End has since been given a new lease of life and is in the process of being brought back from the brink.

This venerable historic plantation house in Leesburg, Virginia sits on 212 acres and dates back to 1700. The mansion was rebuilt in 1902 in a Colonial Revival style by its then-owner Elijah Brokenborough White, who hired the most prestigious artisans he could find to deck out the rooms, which are notable for their fine paneling.

The 20-room house also featured one of America's first intercom systems. White bred champion racehorses at the estate and was wealthy enough to maintain the elegant neo-classical property to a T. During its heyday in the 1920s, the mansion hosted grand balls and dinner parties that were attended by local politicians and other VIPs.

Maaten effectively abandoned the property in the early 2000s. Left to the elements, Selma Mansion began to fall apart. The crumbling house was slowly reclaimed by nature and the interiors were targeted by vandals. Period features were smashed up or stolen, and parts of the roof caved in, as these photos from that time show.

In 2016, local resident Sharon Virts spotted the house on the list and vowed to buy and restore it. Delighting conservationists, Virts and her husband Scott Miller persuaded Maaten to sell and succeeded in acquiring the property for $1.2 million. Rescued from ruin, Selma Mansion is currently being restored to its former glory.
